WIRE VVEAVING LOOM.

SPECIFICATION forming part of Letters Eatent No. 684,536, dated October 15, 1901.

Application filed August 24, 1900. Serial No. 27,883. (No model.)

To all whom it may concern:

Be itknown that I, HIRAM A. Bonn, a citizen of the United States of America,and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in VJireWVeaving Looms, of which the following is a full, clear, and exact description.

In weaving Wire-cloth in looms where the lay is power-operated the result in beating up or battening is not altogether satisfactory owing to the harsh striking of the cross-wires or woof by the reed carried on the lay, this tending to harden and render refractory the wire fabric as so produced.

In the manufacture of wire-cloth the best results are acquired in looms wherein the movements of the lay are imparted by hand, and hence hand-looms are continued extensively in use.

The object of this invention is to devise a power-operating or automatic mechanism for the lay which will have the quality of action in the beating up of a hand-operated lay.

The invention consists in the combination with the loomlay and power-operated mechanism therewith connected for imparting thereto its back-and-forth swinging movements, which is so constructed that in the beating-up movement the lay will be moved positively, as power-impelled, a less distance than to bring the reed against the last shotwire, whereby the final portion of the beating-up movement of the lay may be by its own momentum, which is the same character of movement as the natural hand-imparted motion.

The improvement in wire-weaving looms is sufficiently illustrated in the accompanying drawing, in which the figure is a side elevation especially showing the lay and the means for operating it.

In the drawing, A represents the lay, pivotally mounted and suspended and having the reed a at its lower portion, a: representing the shed and y the battening-point.

13 represents the camshaft, C the cam, and D the cam-lever, engaging the cam in the manner most common in power-operated wirelooms, whereby the cam imparts to the lever reciprocatory swinging motions, as well known.

G represents the connection between the cam-lever D and the lay A. Said connection G is constructed in two sections 1 and 2, the section 1 telescoping into and being endwise movable relatively to the section 2, which latter section has a slot 3 therein, through which is passed the stud or abutment 4: carried by section 1. The one section of the connection Gr therefore has a lost-motion engagement with the other. As the lay swings toward the battening-point before the reed reaches the woofwire the cam-lever has swung to its limit, as has also the section 2 of the telescopic connection G, the stud 4: of said section 1 cansing up to the final movement of said section 2 a movement of section 1 of the same extent, because of the contact of said stud against the end of the slot 3 which is nearest to the cam-lever. Now by reason of the capability of the section 1 to have a distended relation in the connection G the final motion of the lay for beating up will be by its own 1110- mentum, and the reed will therefore strike the wire in such a manner as to give thereto a blow or impact less harsh and violent than would be the case were the lay forcibly carried to the battening point by a positive cam motion.

1 am aware that adjustable connections have been employed in relation to the lay of the loom, so that the swing of the lay may be determined as to the extent thereof. I am also aware that a construction of operating mechanisms for the lay of a loom has been patented, whereby the final motion of the lay is against a yielding spring-pressure, which latter provision in a loom for the work contemplated will be without value, and

What I claim, and desire to secure by Letters Patent, is-- 1. In a loom, the combination with the lay, of the lever and operating-cam therefor to positively move the lay partially to the battening-point and then leave the lay free to beat up by its own momentum, the connection between said lever and lay comprising two sections freely movable with relation to the lay may have free swinging movement by each other Within determined limits. its own momentum to the point of beat up.
